New concept for Simulating the Cavitation Phenomenon by using Sub-grid Model for Characteristic the Fine Structures

Cavitation occurs in liquid flows at the operation temperature, when the local pressure reaches values lower than the vapor pressure, inducing vaporization, this phenomenon causes some potentially negative effects such as: performance deterioration, vibration noise and cavitation erosion. This research is working on the development of new approach for simulating the cavitation phenomenon by using sub-grid model for characteristic the Fine Structures which are used for simulating the cavitation phenomenon which relay on using sub-grid model to characteristic the fine structures whose are responsible for the dissipation of turbulence energy into heat as well as for the molecular mixing, these fine structure gives the space for reactions to occur.
